I can see Notion folder from my desktop Mac but it’s totally invisible from the iphone. Furthermore, Notion keeps on opening Dropbox when I attempt to import a file. I disconnected Notion from Dropbox multiple times but no way: Notion will keep on redirecting me to Dropbox website.It drives me crazy!

Really good observation on Dropbox being the only option for import. Same for me.

I usually Airdrop Notion files to myself, or open "Files" and simply open the files into Notion. Also, anything in the iCloud Notion folder appears in the main Notion window, so if you have something saved in "Notion" on iCloud, it is already there.
